Thomas sits in USDA Zone 6a (-10 to -5°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

What to do before the first frost

Zone 6a around Thomas has about 6 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

Why 05/09 isn't a guarantee

05/09 is the middle of 30 years of NOAA records, not a promise. Plant by 04/24 and you're betting against frost in roughly 9 years out of 10. 05/25 is the safer bet, historically only a 1-in-10 chance of frost that late.
